Unlike traditional methods of disease control, this active ingredient is not a fungicide as it has no direct effect against pathogenic fungi and bacteria. Instead, it acts much like a vaccination. When applied, Acibenzolar-S-methyl triggers the natural defense response, or the Systemic Acquired Resistance (SAR), of the turfgrass by activating production of pathogenesis-related proteins (PR proteins). The PR protein boost awakens the turf’s resistance to biotic and abiotic stresses like drought. In addition, this internal response within the plant enhances its own defense system against certain fungal and bacterial disease attacks. Thus, Acibenzolar-S-methyl bridges the gap between genetic resistance and conventional disease control by activating the plant’s own natural defenses.

This is a good solid fungicide and it works well with other fungicides as well. A unique thing about this one is that you can use this to boost your lawn's own resistance to fungi. I had longer streches where my lawn stayed lush and green, before I had to do another run of the stuff. I use this in between mandatory treatments and my lawn is always looking great.
